Why teams connect Infor M3 and Plex ERP

Two ERPs, one set of facts: Stacksync keeps Infor M3 and Plex ERP consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Purchase Orders, Manufacturing Orders, Inventory Balances, Invoices in Infor M3 with Production jobs, Sales orders, Purchase orders, Customers in Plex ERP bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • 01 Feed manufacturing order status to a customer portal for order tracking in fashion, food, or equipment supply chains
  • 02 Keep supplier and purchase order data aligned between M3 and procurement tools
  • 03 Mirror purchase orders and receipts to accounting or planning tools.
  • 04 Feed quality and scrap data to dashboards supervisors check without logging into Plex.

Common sync patterns

Two-tier roll-up

Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

What you can sync between Infor M3 and Plex ERP

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Infor M3 objects Plex ERP objects How this pairing syncs
Customers Customer master records sync with CRM account records to keep one shared customer file. Customers Account records kept consistent with the sales team's CRM Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Suppliers Supplier records align procurement tools with the vendors M3 purchases from. Suppliers Vendor records aligned with procurement and AP tools Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Purchase Orders PO headers and lines sync outward so buyers and receiving teams see the same demand. Purchase orders Procurement records mirrored to accounting and planning systems Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Warehouses Warehouse and facility records scope inventory and order data during mapping. Quality records Checksheet and inspection data pulled into plant dashboards Warehouses is specific to Infor M3 and Quality records to Plex ERP — each maps to any object or custom field on the other side.
Price Lists Pricing data keeps quoting tools consistent with the prices M3 will actually invoice. Parts Item master records shared with CRM, e-commerce, and planning tools Price Lists is specific to Infor M3 and Parts to Plex ERP — each maps to any object or custom field on the other side.
Items Item master records provide the SKU, unit, and attribute data other systems price and sell against. Inventory On-hand balances and locations replicated for visibility outside the plant system Items is specific to Infor M3 and Inventory to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Infor M3 and Plex ERP

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Infor M3 Plex ERP Sub-second propagation

DetectionInfor M3 notifies Stacksync of record changes through webhook events. Event publishing through Infor ION (Business Object Documents), configured in ION, or scheduled polling of API endpoints.

DeliveryEach detected change is written to Plex ERP through its API, with automatic retries and rate-limit backoff.

Plex ERP Infor M3 Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is written to Infor M3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Infor M3: Subject to Infor ION API gateway throttling policies.
  • Plex ERP: Subject to the platform's API rate limits.
